Note

Low Risk
Low risk dependency bump limited to the ext/app_bridge Rust crate; main risk is runtime/build compatibility changes from the Wasmtime major version upgrade.

Overview
Updates ext/app_bridge to use wasmtime 44.0.1 (from 43.0.1) by changing the dependency version in Cargo.toml.

No other code or dependency versions are modified in this PR.
